Public Member Functions
MAYAFLUX_API void	attach (Layer &layer, uint32_t body_id) const
	Relate a body element to this collapsible and sync its visibility to the current open state.
Collapsible &	closed_color (glm::vec3 c)
Collapsible &	initially_open (bool v)
Collapsible &	label (std::shared_ptr< Core::VKImage > img)
	Attach a GPU image overlaid on the header as a text label.
Collapsible &	open_color (glm::vec3 c)
MAYAFLUX_API Collapsible &	place (std::shared_ptr< Buffers::FormaBuffer > buf, Surface &surface, LayoutCursor &cursor, float x_min, float x_max, float row_h)
	Register the header element and wire the toggle callback.

Public Attributes
std::shared_ptr< Buffers::FormaBuffer >	buf
	FormaBuffer backing the header geometry. Valid after place().
LayoutCursor	cursor_out
	Cursor positioned below the header, ready for body elements. Valid after place().
uint32_t	header_id {}
	Element id of the header strip. Valid after place().
glm::vec3	m_color_closed { 0.25F }
	Background color when closed. Default: glm::vec3(0.25F).
glm::vec3	m_color_open { 0.35F }
	Background color when open. Default: glm::vec3(0.35F).
bool	m_initially_open { true }
	Starting toggle state. Default: true (open).
std::shared_ptr< Core::VKImage >	m_label
	Optional GPU image overlaid as a text label. nullptr = color only.
std::shared_ptr< MappedState< bool > >	open
	Open/closed state. Valid after place(). Write to toggle.

Detailed Description

A collapsible header strip.

Before place() is called, the struct carries only configuration. After place(), header_id, open, buf, and cursor_out are populated. This mirrors the Element pattern: configure with setters, register with a single explicit call.

auto col = Collapsible{}
    .initially_open(false)
    .closed_color({ 0.2F, 0.2F, 0.2F })
    .label(header_img)
    .place(window, layer, ctx, cursor, x_min, x_max, row_h);
 
col.attach(layer, body_id);
